What stands out

What we found in Vega de San Mateo

It comes from matching each building with its neighbourhood, its street, the nearest watercourse and its surroundings.

1

4.149 homes at very high wildfire risk

4.129 buildings

These are 4.129 buildings right next to vegetation that can burn. Of these, 7 are blocks of flats with 202 homes, where evacuation is harder.

  • Calle Párroco Manuel De La Coba Socorro: 50
  • Calle La Montañeta: 35
  • Calle Lourdes: 29
  • Calle El Cantillo: 24

Proximity to woodland and to burnt areas (ESA WorldCover, EFFIS). It does not measure the state of the vegetation or any firebreaks.

2

Where there are fewer trees, 3,4 °C hotter

3,4 °C

Around homes with between 10 and 20 % tree cover, the surface in summer is 2,9 °C above the median for Vega de San Mateo; with more than 40 % tree cover, 0,5 °C below. 0 homes are in surroundings with almost no trees.

Ground surface temperature (Landsat), not air temperature. More trees usually go with less asphalt and lower density: this is a correlation, not a measure of the effect of planting trees.

3

From 49 to 67 tropical nights a year

49→67 nights

In a typical building in Vega de San Mateo, nights when the temperature stays at or above 20 °C would rise from 49 a year (1991-2020) to about 67 by 2050. For this reason, 100 % of homes would be at a high or very high level.

Barranco de Los Chorros: 212 homes less than 50 m away, with no official map

212 homes

Along Barranco de Los Chorros (4,9 km within the municipality, dry most of the year) there is no official mapped flood zone, but there are 212 homes less than 50 m from the watercourse.

Having no official map does not mean it cannot overflow: watercourses that are dry most of the year are the ones that cause the most surprises in a storm.

5

49 in every 100 buildings were built before 1980

49 %

They were built before the first thermal insulation standard (1979). With 67 tropical nights a year by 2050, they will hold the most heat at night and have the most to gain from a retrofit.

What can be done

For the town council and for residents

For the town council and its technical staff

  • Climate shelters, and late-afternoon and evening opening hours at libraries and community centres in the areas with the most tropical nights.
  • Shade and trees in the playgrounds of the 1 schools with the hottest surroundings.
  • Review with the river basin authority the watercourses with no official mapping that run next to homes, and keep them clear.
  • Firebreaks and evacuation routes in the streets that border woodland.
  • Download the tables by area, neighbourhood, street and watercourse (Data tab) to cross-check them with urban planning.

For residents

  • Air your home in the early hours, shade west-facing walls from the sun and ask about grants to insulate the roof.
  • If you live on a ground floor or have a garage next to a watercourse, have a plan: where to go upstairs, what to switch off and how to hear about warnings.
  • Keep the strip around your house clear of dry vegetation and know both ways out of your street.
  • Look up your building: the free report gives its level for each hazard, and the Climate Note gives the full detail.
